Question

what is the answer in the equation 4x+y=6 and y=6-4x?

Answer 1

they are the same

Answer 2

wh answer? O.o

Answer 3

they are the same equations

Answer 4

Erm, through what process, exactly?

Answer 5

subtract 4x from both sides

Answer 6

so the answer is indefinite?

Answer 7

yah, in a system of equation

Answer 8

indefinite?
if this is a system of 2 equations then there are infinite solutions

Answer 9

so whats the answer?

Answer 10

I'll arrange it first. ((I followed this pattern: x + y = 6. So, in the second equation, which is y = 6 - 4x, I transposed -4x so that it will follow the pattern. Thus, negative will become positive. This is what turned out.))

4x + y = 6
4x + y = 6

ELIMINATE X ((Since they have the both signs, the process is subtraction.))

4x + y = 6
- 4x + y = 6
= 0x + 0y = 0

x = 0

ELIMINATE Y ((Choose just one in either of the equations. Replace the x in here with the x you came up with in the past equation. Then proceed.))

4x + y = 6

4(0) + y = 6

0 + y = 6

y = 6

SO. x = 0
y = 6

Hope that helped.

Answer 11

thank u very much alexfeb:)

Answer 12

No problem. (: Though, this process is only for finding x and y through elimination. Be careful if this wasn't the thing you were looking for.

Answer 13

no thats wrong, well it is a solution but not the only solution
other solutions are:
x=1,y=2
x=3, y=-6
...
in elimination if you have the situation
0x+0y = 0
it means infinite solutions, the equation are the same, Not x=0
